EQUALIZER.

Application filed March 16, 1923. Serial No. 625,683.

To all fui/tom it may concern:

Be it known that I, Jox-1N H. GIBSON, a citizen of the United States, residing at Bruin, in the county of Butler and State 'of Pennsylvania, have invented a new and useful Equalizer, of which the following is aspecification.

This invention relatesto well pumping apparatus, the primary object of the invention being to provide a hollow section to be 'included in the sucker rod construction, the hollow section being provided with openings establishing communication between the interior of the tubing and the hollow section.

Another object of the invention is to provide a device of this character which may be readily and easily substituted for one of the solid sections of the sucker rod.

IVith the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing:

Figure 1 is a fragmental sectional view through the tubing and disclosing the sucker rods equipped with a device co-nstructed in accordance with the invention.

Figure 2 is a sectional view taken on line 2--2 of Figure 1.

Figure 3 is a fragmental sectional view disclosing the method of connecting the upper end of the hollow tube and the ad jacent section of the sucker rods.

Figure 4 is a fragmental sectional view disclosing the connection between the tubular section and the adjacent lower section of the valve stein at the top of the working barrel.

Figure 5 is a sectional view on line 5-5 of Figure 1.

Referring to the drawings in detail, the reference character 5 designates a tubing in which the usual sucker rods operate. The sucker rod in the present case, is indicated at 6 and embodies a plurality of connected sections. The device forming the essence of the invention is indicated at 7 and is in the form of a tubular section that has a head 8 55 welded or otherwise secured to the upper end thereof, which head has a reduced threaded extension 9. This threaded extension 9 is positioned in the threaded opening 10 of the adjacent upper section of the 60 `sucker rod whereby the tubular section 7 may be secured thereto. i

At the lower end of the section 7 is shown a section of the valve stem protruding from the working barrel beneath which is formed a threaded extension 11 positioned in the threaded opening 12 of the head 13, which is also welded to the tubular section 7. Disposed in the wall of the tubular section 7 are openings 14 which openings are ar- 7o ranged spirally in the section 7, the same being disposed in spaced relation with each other to provide communication between the interior of the section 7 and space in the tubing 5 between the walls of the tubing 75 section 7.

IVhat is claimed as new is:-

An equalizer including a tubular section having threaded end portions adapted for connection with a sucker rod, the wall of Said tubular section having openings formed therein, and said openings being disposed spirally of the tubular section throughout a portion of the length of the tubular section.

In testimony that I claim the foregoing as my own, I have hereto aiiixed my signature in the presence of two witnesses.
